V SNAKE-POISON EXTRACTOB.

Application fil ed August 26, 1921. Serial No. 495,686.

To all whom it may concern:

-Be it known that STEPHEN O. BRYANT, a citizen of the, United States ofAmerica, re,- siding at Bethan in'thecounty of Harri- 6 .son and Stateof issouri, has invented new and useful Improvements in Snake-PoisonExtractors, of which the following is a specification.

The object, of the invention is to provide 10 a simple and effectivemeans for extracting the poison due to snake and other bites from thewound as an emergency means of preventing the poison from passin intothe blood circulation of the victim an .as a sub-' stitute for themethod occasionally followed of sucking the wound with the attendantrisk 'to the rson who resorts to this expedient and w 'ch usually provesfatal in the event that there should be any out or abrasion of the lipsof the person applying such remedy; and with this object in view theinvention consists in a 'construction and combination of arts of which apreferred ,embodiment is s own in the accompanying '25 drawings, whereinF1 1 vis a side view and Figure 2 is a longitudinal sectional view .ofan instrument embodying the invention.

Figure 3 is a transverse sectional view of so the same.

Figure 4 is a viewpartly in side elevation and partly in section shown?la modifieation of the-invention such as W1 obtain in t H v manuiacturebf the invention small units.

- The device consists of a cylindrical. or tubular body 10 and a'vacuumchamber 18,

r I this body preferably having a fla'mouth piece 11 for arrangement inair tight con- 40 tact with the surface of the body of the victim aroundthe abrasion formed by the bite or stroke of the snake or other animal.Thisimou'th piece is preferably of rubber to permit of compression toenable the engage- 46 merit on parts of the body on which a stronsuction could not beobtainedif the mout .piece were of metal, althou hon fleshy parts of the body a metal mout piecexwould serve the dpurposeof the invent1on.,.

. The b0 y portion 18 isQformed adjacent the mouth place with .a'laterally vacuum cup in communication wit vacuum chamber and constitutan mter- 1s a means for; exhausting ber 18' to wit a nipple the vacuumchamber, a pump is employed and consists of a tubular element 10 securedto the vacuum cu by the lateral members 10 and 10" of which the formeris of tubumember, t is ring servin as a means to permit the operation oft e plunger. The lunger is provided with a'flexible packing P disk 16designed to fold rearwardly during a the forward stroke of the plungerto sprea and form an air tight contact with the surface of the barrel onthe return or operative stroke, so as to produce a forcible suction toexhaust the air from the vacuum chamber and consequently produce asuction in the flared mouth piece to extract venom or poison from thewound for venom cup 12.-

In the operation of the invention the flared mouth pieceis placed overthe wound and the operation of the pump immediately begun. Air is thusextracted from the vacuum chamber 18 by the pump with the result that asuction is created on the wound and the poison extracted from the latterpassed to the vac'uumchamber and removed in the venom cup in which itfalls. A'fter the completion of the o ration of extracting the poison,the slig t loosening of the cap constituting the venom cup will admitenough air to the vacuum chamber to relieve the suction on the wound andthis permit the ready withdrawal of the mouth 11 from the wound.

In Figure 4 there is shown a modification of the invention in which thevenom cup and the pump are combined. The tubular so reception hythemember 18' carries the plunger 13' and the latter is provided with astem 14' ing through the rear "of the tubular mempermit the.manipulation of the plum er to create a vacuum in the tubular mem r andthus a suction in the discharge mouth 11'.

Having described the invention, what is claimed as new and is:

l ison extractor comprising a cylinprotrudbarrel closed at one end' andopen at" its oppesite end, a cone sha I mouth piece inserted in the openend. 0 the barrel and havi its axis in longitudinal alinement with t eaxis of the barrel, said mouth piece 5 beinicomposed of relatively ri 'dmaterial and aving tapered walls whic are thick- I est'at the innersmaller end of the mouth iece, the. parts being so arranged that thearrel may be used as a handle for forcing E the larger end of the mouthpieminto the neeee'ze flesh whereby the wound therein is forced up intothe mouthpiece and o ened, means for rarifying the air in the arrel anda venom cup projecting laterally from the barrel adjacent the mouthpiece and communicating interiorly with the barrel,

In testimony whereof he afixes his signature.

STEPHEN e. BRYANT.
